◆ RNTupleJoinProcessor() [1/3]

ROOT::Experimental::RNTupleJoinProcessor::RNTupleJoinProcessor	(	std::unique_ptr< RNTupleProcessor >	primaryProcessor,
		std::unique_ptr< RNTupleProcessor >	auxProcessor,
		const std::vector< std::string > &	joinFields,
		const RNTupleProcessorOptions &	opts )

private

Construct a new RNTupleJoinProcessor.

Parameters

[in]	primaryProcessor	The primary processor. Its entries are processed in sequential order.
[in]	auxProcessor	The processor to join the primary processor with. The order in which its entries are processed is determined by the primary processor and doesn't necessarily have to be sequential.
[in]	joinFields	The names of the fields on which to join, in case the specified processors are unaligned. The join is made based on the combined join field values, and therefore each field has to be present in each specified processor. If an empty list is provided, it is assumed that the processors are fully aligned.
[in]	opts	Options for the processor.

◆ RequestField() [1/2]

RNTupleProcessorOptionalPtr< void > ROOT::Experimental::RNTupleProcessor::RequestField	(	const std::string &	fieldName,

		void *	valuePtr = nullptr )

inlineinherited

Request access to a field for reading during processing.

Parameters

[in]	fieldName	Name of the requested field.
[in]	typeName	Type of the requested field.
[in]	valuePtr	Pointer to bind to the field's value in the entry. If this is a `nullptr`, a pointer will be created.

Returns: An void-type RNTupleProcessorOptionalPtr, which provides access to the field's value.

Warning: Provide a valuePtr with care! Values may not always be valid for every entry during processing, for example when a field is not present in one of the chained processors or when during a join operation, no matching entry in the auxiliary processor can be found. Reading valuePtr as-is therefore comes with the risk of reading invalid data. After passing a pointer to RequestField, we strongly recommend only accessing its data through the interface of the returned RNTupleProcessorOptionalPtr, to ensure that only valid data can be read.

template<typename T >

RNTupleProcessorOptionalPtr< T > ROOT::Experimental::RNTupleProcessor::RequestField	(	const std::string &	fieldName,

Template Parameters

T	Type of the requested field.

Parameters

[in]	fieldName	Name of the requested field.
[in]	valuePtr	Pointer to bind to the field's value in the entry. If this is a `nullptr`, a pointer will be created.

Returns: An RNTupleProcessorOptionalPtr of type T, which provides access to the field's value.

Warning: Provide a valuePtr with care! Values may not always be valid for every entry during processing, for example when a field is not present in one of the chained processors or when during a join operation, no matching entry in the auxiliary processor can be found.
